If you think MDO is a prescription for how the US will fight, think again. Colonel (retired) Richard Creed, Director, Combined Arms Doctrine Directorate at Fort Leavenworth, explains how the concept has evolved since 2018 culminating in the publication of FM3-0 in 2025. Rich also explains how and why the NATO concept differs so much from the US one, and why the US can't simply make their doctrine into one for the Alliance. Covering the five approaches, the levels of applicability, and the command and control conundrum of MDO for the US Army, the conversation focuses on authorities and responsibilities as much as the philosophy of warfighting. Fascinating stuff.
